Anyone who’s a cannabis connoisseur or simply canna-curious but feels overwhelmed by all the choices in weed out there can benefit from a shortcut that Head discovered: your eye color. Many scientists have concluded that certain eye colors match certain personality traits. By using anecdotal evidence of the effects of certain weed strains, we were able to match specific strains to personality types.

Wait a second though – couldn’t you simply buy a weed strain based on your personality type? Why would you add the step of factoring in your eye color? Two reasons. First, it spares you the self-analysis and dependence on your own self-awareness to decide on which strains to buy.

And second, it’s probably something you haven’t tried before and might be a fun experiment. Even the most introspective toker can find pleasure in indulging in the simplicity of using eye color to curate a weed sampler – no?

So, if your physician has given you the OK to consume cannabis, read on to draw up your weed-strain shopping list!

What creates your eye color?

Your eye color results from the amount and distribution of the brown pigment in the protective protein (i.e., melanin) in your iris, which itself is the result of three genes. Interestingly, according to the American Academy of Ophthalmology, how much melanin is in your iris and how it is distributed is unique to each person, comparable to fingerprints. Otherwise put, no one but you has your exact color of eyes.

As is the case with skin and hair, the more melanin you have, the darker the color that manifests. (Unlike skin and hair though, the eyes don’t produce pigment continuously, leaving your eyes to change color over time.)

People whose irises have a lot of melanin have brown eyes; people whose irises have less melanin have blue, gray or green eyes; and people whose irises have extremely little melanin (ocular albinism) appear to have violet or red eyes because what’s visible are the blood vessels. That’s when color is simple to determine.

If you can’t decide on which color your eyes are, or if you find that they change from day to day or hour to hour, it means that the melanin in your iris is distributed unevenly. (There’s a lengthy scientific explanation for that, but let’s not get sidetracked.) Often, eyes with that melanin distribution are described as “hazel.” For greater precision though, you can use an app that scans your eyes to tell you which color they are (kinda creepy, but an option nonetheless), or you can consult an eye color chart.

You can tell whether you have hazel eyes if you would describe them as a combination of brown, green and gold – sometimes blended together, and other times solid brown, green or gold. Hazel eyes change depending on the surrounding light (due to Rayleigh scattering), as well as the presence of certain colors in the clothing and/or makeup that a hazel-eyed person wears.

Curious about how common your eye color is? Here’s what WorldAtlas says, from among the world’s estimated 8 billion people:

  • Brown: 70% to 80%
  • Blue: 8% to 10%
  • Hazel: 5%
  • Amber: 5%
  • Gray: 3%
  • Green: 2%

Is there a legitimate link between eye color and personality?

Does your eye color really match certain personality traits? Or is it just another pop-psychology fad for consumption when you’re bored enough to be open-minded? There are skeptics, of course, typically attacking the testing methods for having too small a sample size or only subjective input. But many educated people find the connection entirely plausible.

Dr. Anthony Fallone of Edinburgh University put it this way: “The eye is so closely linked neurologically to the brain that you might call it the only part of our brain you can see from the outside. It seems to hold vital clues to our brain function.”

Building on that, scientific studies conducted in Sweden at Orebro University discovered that the same genes that form our frontal lobes are the genes that affect our eye color. The study concluded: “[P]eople with different iris features tend to develop along different personality lines. These findings support the notion that people with different iris configurations tend to develop along different trajectories in regards to personality.” Similarly, analyses of mutations of the gene PAX6, which controls the formation of the eye in the early stages of embryonic development, revealed a link between eye development and neurodivergence.

Far-fetched? Perhaps. Impossible? Definitely not.

  • Super Lemon Haze: Boosts your energy to keep the party going late into the night.

Give it a try!

Sometimes it’s fun to surrender control and go with the flow, allowing something outside yourself to make a decision for you – and being OK with accepting whatever that decision is. Here’s a low-stakes opportunity to give that a try. Open your mind. The next time you’re browsing your weed selections, ask the “windows to your soul” what they’d like. You might become a little more self-aware in the process of becoming a little less self-restrained, courtesy of your irises.
